Abstract

A sintered metal fiber medium as subject of the invention comprises at least a first metal fiber layer providing a first outer surface to the sintered metal fiber medium. The first metal fiber layer comprises metal fibers with an equivalent diameter D 1 . The medium has a mean flow pore size of less than 2 times the equivalent diameter D 1 . The metal fibers in the first metal fiber layer in the sintered metal fiber medium have a ratio of average fiber length L 1 over diameter (L 1 /D 1 ) which is preferably less than 110.
